Ryobi Automatic Emergency Light

April 3, 2023

Check out the video above for a quick look at the project. The video below shows you in detail how to build it! Recently, I had been thinking about emergency lighting. In the case of a blackout, the first thing a person needs is light, even if it’s just to get to your junk drawer […]

LED Headlight Fail!

April 10, 2019

One of the upgrades I made after purchasing my Mitsubishi iMiEV electric car was to install LED headlights. Well, today, the second of the two LED headlamps failed! I had to take a look at my blog to remember when I actually DID install the headlights. Turns out it was just over three years ago. […]

LED Headlights

January 8, 2016

Recently, I did a few small LED lighting upgrades to my electric car. Those went well, so I thought I would tackle the big one: Installing LED DRIVING LIGHTS! And I thought it would be easy…. The car has separate bulbs for the low beam, high beam, and parking light. My plan was to upgrade […]

At home, I have a small LED light that is designed for use under cabinets. I use it mostly to illuminate one side of my aquarium, and I occasionally pull it out to use it as a light for filming video. The problem is that it is quite a bit brighter than the other LED […]

PWM DC Motor Controller / LED Dimmer

April 21, 2011

Last week, I started work on a very basic DC Motor Controller.  It’s a really simple circuit that just turns voltage on and off, but very quickly (like about 1000 times a second..) By varying the time off vs time on of the circuit, a Light Emitting Diode (LED) can be dimmed, or a DC […]

World’s Simplest PWM Motor Controller

April 16, 2011

Well, I did it! Knowing nearly nothing about electronics, I managed to finally build my own PWM (Pulse-Width-Modulation) DC Electric Motor Controller! OK, that makes it sound way too fancy. At the beginning of the semester, I signed up for a non-credit electronics class at the local two-year technical college. I’ve been wanting to take […]
